reactjs – React – fetch-intercept修改所有头文件

拦截所有请求并使用fetch-intercept反应添加标头的正确方法是什么？我有一个配置文件,其中包含对fetchIntercept.register()的调用.我有用于导入fetchIntercept配置文件的组件api调用的单独文件.我在调用api之后添加了unregister()调用,但是没有添加标头.

API / config.js

import fetchIntercept from 'fetch-intercept';

const unregister = fetchIntercept.register({
    request: function (url,config) {
        // Modify the url or config here
        const withDefaults = Object.assign({},config);
        withDefaults.headers = defaults.headers || new Headers({
          'AUTHORIZATION': `Bearer ${JSON.parse(sessionStorage.credentials).authToken}`
        });
        return [url,withDefaults];
    },requestError: function (error) {
        // Called when an error occured during another 'request' interceptor call
        return Promise.reject(error);
    },response: function (response) {
        // Modify the reponse object
        return response;
    },responseError: function (error) {
        // Handle an fetch error
        return Promise.reject(error);
    }
});

export default unregister;

API / packageApi.js

import unregister from '../api/config';

class PackageApi {

  static getAllPackages() {
    const request = new Request('/get/my/packages',{
      method: 'GET'
    });
    return fetch(request).then(response => {
      return response.json();
    }).catch(error => {
      return error;
    });
  }

}
unregister();

export default PackageApi;
